Alkali metal Wikipedia

The alkali metals consist of the chemical elements lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr). Together with hydrogen they constitute group 1, which lies in the s-block of the periodic table.All alkali metals have their outermost electron in an s-orbital: this shared electron configuration results in their having very similar characteristic properties.

inorganic chemistry Why is lithium the most reducing

Apr 12, 2015  Lithium has a higher reduction potential. If you also look at the electronegativities of just Lithium and Cesium then you would notice that the shielding effect is more prevalent in Cesium, thereby reducing the electronegativity and affecting the reduction potential. So Lithium however, just compared to Cesium, has a higher electronegativity.
